I'm hoping someone can answer this..
I am wanting to buy the MTH DCS Remote Control Set [50-1001]. I was looking online and there are a few older/used ones, but the state they're the "OLDER" non-USB version. They have a 9-pin serial plug instead. I know what both of those things are.
My question is - Besides the non-USB, does the Older (pre-2010) version of DCS 50-1001 have any performance or capability differences than the "Current" version of DCS?
